We know that James Cameron tried to make a gritty, adult Spider-Man movie in 1992 (see: the Spidey and Mary Jane sex scene on the Brooklyn Bridge). But what would this thankfully averted train wreck have looked like?
Wonder no longer, true believers. Techland has dug up concept art from Cameron's treatment, and the results are equal parts "sort of cool" and "resoundingly creepy." Say what you will about Spider-Man 3 - at least evil swing-dancing alien symbiote Peter Parker was never a peeping Tom. Also, note the scrapped storyboard featuring Spidey antagonist Electro!
